Temporary tables are special, they require strict
single-threaded use as they have no locks protecting concurrent
access. Therefore, we cannot safely use the optimization of
overlapping the commit of this transaction with the start of the
following.
So we skip the early mark_start_commit() and also block any
wakeup_subsequent_commits() until this event group is fully
done, inside finish_event_group().
